Ina-n a Houseman,

mittent stripes or figuredell'ects. Yarn is fed to a circle of needlesin such relation as' will cause the needles, when in normal osition, toknit regular plated fabric. f en selected needles are pushed back, thevneedles will knit'th'e yarn in a reversed relationship and thus producereverse Y lated fabric in the wales knit by such nee es 4while they arepushed back. Thepresent invention comprises automatic pattern-controlledmechanism particularly adap1 ed for actuating the mechanism set fort inthe Wilbur L. Houseman application. i.

Figs. 9, 10 and 11 are detail views, in diere'nt positions, of the levermechanism lconstitutin part of my invention.

I shall 1rst describe themechanism for selectively pressing back needlesdevised by :Wilbur L. Houseman and illustrated in Figs. 6, 7` and 8, andshall then describe the pattern-controlled means that I have devlsed foractuating said mechanism automatically.

Vertically slidable in slots of the revolving needle cylinder a are theneedles b which are movable up .and down in anormal knitting wave bycams not shown. .Fastened to the needle cylinder is the sinker dial 0,which carries the'sink'ers or web holders b', which cooperate with theneedles in the usual manner to-form the stitches.

Below the sinkerdial c is a slotted jack dial d, which is attached tothe sinker dial. Press- -erse are plcaed in' the needle cylinder slotsafter the needles have been inserted and are held in place by the twospring bands 60. These pressers are so shaped that they bear against theneedles at the extreme upper ends of the pressers and also at pointsopposite the spring bands 60. The needle cylinder slotsare of greaterthan normal depth at their upper ends, forming shoulders 62. The needlesare unsupported above these shoulders, which act as fulcrums whenneedles are l .pushed back by the upper ends of pressers e. The jackdial d has slots corresponding in .number with the slots in the needlecylinder.

At intervals and in groups in accordance with a knitted fabric, jacksfare inserted in the dial slots. These jacks are held lightly in contactvwith their corresponding needle pressers e lby a spring band 61.

pattern which is to be formed in the A threaded clamp ring h holds thejacks'in their propervertical position. The jacks are formed with slotson their rear ends so that sections may be broken out in dierent placesleavin butts f which may be in any one of eight ifferent verticalpositions. If desired, .there may be two or more butts on a Jack.

The one illustrated in Fig. 7 has butts in all eight plositions, whereasthe one shown in Fig. 6 as a butt in the second highest posi.- tion. v

The ei ht cams gv g1, g2 g. g g5, gea g1, d0 not revo ve and may bemoved into or out of the ath of the butts of the jacks f, each of theeig At cams being in alignment with one rock them in a clockwisedirection, so that extensions la on these levers will ride u on of thecorresponding eight butt locations on the jacks.

When one or more of the eight cams g, g1, g2, g3, g, g, g, g?, are movedand held in the path of the jacks having butts corresponding to thevertical positions of such cams, these jacks will be pushed inward andwill in turn rock the corresponding pushers e, thereby springing thecorresponding needles at the fulcrum point 62, causing their hooked endsto be set back out of line with the adjacent unpushed needles.

I shall now describe the mechanism-which I have devised to selectivelyrender the` 'ack cams g, g1, etc., active or inactive to pr uce figuredreverse plated effects.

In Fig. 3, these cams are shown pivoted on a stud 50. Pivoted on a studi, which is'on a bracket attached to the-machine frame, are eight leversj, one foreach of the cams g, g1, etc., and in vertical alignment withsaid cams. Springs Z, one for each lever, tend to similar extensions onthe jack cams, ren ering said cams active by pushing them toward thejack dial and thus in the path of butts on the jacks. Adjusting screwsm, one for each lever, enable a fine adjustment of the pushing cams tobe made so that needles will be sprung back just the proper distance.Levers y' have slotted holes where they pivot on stud i so that theywill move toward or from the jack cams when screws m are adjusted. Thesides of these levers where they bear against screws m are curved so asto follow a true radius from stud z'.

Pivoted on stud 51 in alignment with the eight levers j are eightstepped levers n, 11.1, etc., one for each lever j. When these levers n,nl, etc., are rocked in a clockwise direction, their correspondinglevers j are moved in a counter-clockwise direction, whereby shoulders kdisengage the projections on the corresponding jack cams g, g1, etc.,thereby ren dering said cams inoperative. When, however, levers n, n1,etc., are rocked in the opposite direction, the ends of levers n, nl,etc., fall into recesses in their corresponding levers j, therebypermitting springs Z to function to render said levers j active to pushcorrespending jack cams into operative position.

From the foregoing, it will be seen that the swinging of levers n, 11,1,etc., in one direction or the other will determine whether correspondinglevers j and jack cams shall be inoperative or operative. I shall nowdescribe the means employed for positively moving the levers 1L, 11,1,etc.

Pivoted on a stud fastened to the frame of the machine are eight bellcrank levers 1',

' r1, etc., (see Figs. 3, 4, 9, 10. and 11). These levers are in twogroups of four each, being spaced apart by a sleeve a (see Fig. 4), and

their long ends are curved to embrace each of the stepped levers 1111,1, etc. As the ends of the levers n, 11.1, etc., are formed with uper and lower cam faces, levers 1', 11, etc., w en moved forward willslide up and beyond the upper cam faces and rock levers 111,11), etc.,in a counter-clockwise direction and hold them in this position. Whenlevers 1, 11, etc., are moved in the opposite direction, levers n, 11,1,etc., will be moved in a clockwise direction, through the action of saidlevers 1', 11, sliding along the lower cam surfaces of levers n, 11,1,etc.

The movement of the levers 1', 11, etc., back and forth is limited byapin p extending through aligning holes in the levers. Levers 1', 11,etc., which, as before mentioned, consist of an upper set of four and alower set of four, are operable respectively by eight levers t, t1,etc., .which are also grouped in upper and lower sets of four each.These levers t t1, etc., are pivoted between their 9 against al sto 'von lever 30 by means of a spring lw. Inf igs. 10 and 11, to avoidconfusion, only two sets of levers 1t, nl, 1*, 11, and t, t1 are shown..In Figs. 4 and 5 the groups of these levers are illustrated.

Each of the levers t, t1, t2 and t3 of the top group is operated b 'aselector A20, which 1s movable laterally, y means to be hereinafterdescribed, and vertically as shown in dotted lines, Fig. 5, toselectively actuate any of said levers. A similar selector 21 operatesin identically the same manner to selectively operate each of the leverst4, t5, t and t7 of the lower group.

Let it be assumed that all of the eight jack cams g, g1, etc., areinactive and that it is desired to render the to and thatlevers t, 1,1r, and 7 are adapted to effect this shift. Selector 20 is moved intoalignment with lever t while lever 30 is moved forward (that is, in adownward direction in Figs. 9, 10 and 11). In the backward or upwardmovement of lever 30, lever t contacts with selector 20 before lever 30completes its movement, and during the completion of the upward movementof lever 30, selector 20 presses lever t down from its normal position(the upper dotted line position in Fig. 10) to a somewhat lower position(the other dotted line position in Fig. 10), during whichy limiteddownward movement of lever t, it contacts with the extreme tip of lever1 and thereafter snaps over it; the selector 20 (which is held inoperative position by a spring 22 that is stronger than spring w)yielding slightly to allow lever t to yield suiciently to enable it toclear the tip of cam g activev thereb carryin lever t out of'contactwith the se ector. hereupon, as lever continues to move down, lever rhasta cam action),A on lever t'andswings it against the ull of.

ycompletion o the downward movement of lever 30, lever t is confinedbetween lever r and stop av, andexerts a positive cam action on lever 1'and tiltsl it down on its axis, as shown in Fig. 11, thereby swinginglever n into position to release lever j, which is' swung by its springl to render jack vcam active. In the upward'movement of lever 30, levert will release lever r, and if selector 20, in the meanwhile, has beenshifted,.lever t will be retracted, by its spring 1p, to the positionshown in Fig. 9; but lever r will not be retracted because its end hasmoved beyond the upper cam angle on lever n. It is desired that lever rshall maintain its advanced pgsition until another chain of levers shallactuated by the selector 20, and that lever r shall be retracted at thesame time that another lever r1, r2 or r is advancing. This isaccomplished by causing any of the levers `t, t1, t2 or ts in themovement by which it ac lvances its corresponding lever r, r1, r or r toswingthe other levers t, t1, t, t in the group, lnto position to retractany of the levers 1', r1, r2, or 1' that may be in advanced position.

To make this operation clear letit be assumed 'that leverr1 has beenadvanced, that lever 30 is in the down position (Fi 10), that lever t isin the position shown in gig. 9, that selector 20 is shifted to alignwith lever t, that lever 30 moves u that lever t contacts'with theselector 'an is thereby moved a. short distance, that lever 30 starts tomove down, that lever t snaps over lever r, and that aslever 30completes its down movement,4

lever 7- is advanced-all as hereinbefore explained. It will beobserved,'by reference to Fig. 9, that each lever t, t1, t2 and t isforked at one end thereof, that stop lv acts to limit the movement inone direction of levers t, t1, t2 and t by contacting with the lowerfork, and that on the shaft carryin levers t, t1, t2 and t3 is pivotedan arm provi ed with a pin s, which engages the upper fork of any of thelevers t, t1, t and t that is in its normal position. Assuming that, asabove described, lever 30 is completlng its downward movement and thatlever t is swinging from the sition shown in Fig. 10 to that shown inig. 11. In Fig. 10 it will be observed that the lower fork of lever thas contacted with pin z. Therefore, as lever t swings from the positionshown in Fig. 10 to the position shown in Fig 11, its lower forkactuates pin z. Pin z contacts with the up er forks ofthe other leverst1, t and t3 an yswings them into theA ition in which lever t1 is shownin Fig. 11. f, as above assumed, lever r1 vis in its advanced position,lever t1 will contact with lever rl and swin it into the ositionoccupied by lever r1 in ig. 11, there causing the ar end of lever r1 vtoslide onto t e under cam face of lever n1 at the same time thatl thenear end of lever "r is riding down below the u per cam face of lever n.The retraction of `over r1 willthus, through lever n1 and the lcorresnding lever j render jack cam 1l.inoperative, whereas the simultaneous avancement of`lever 1- will, through lever n and the corresponding lever(j throu h the action of the corresponding spring render jack cam goperative.

As above mentioned, levers t, t1, t and t' are s aced above the lowergroup t", t, t and t', t e upper oup being controlled by selector 20 andthe owerfgroup by selector 21.

"Ihese selectors are operated by separate pattern mechanisms to behereinafter described, 4so that a selection may be made in either the upr or lower groups independently or, if dsired, simu taneously. It is'therefore possible to render any one of the upper four cams g, g1,etc., active by the operationof the upper selector 20, or any one of thelower four of said cams active by the op'- eration of the lower selector21, or one of t e upper four and one of the lower four of said camssimultaneously active by the simultaneous action of both selectors.

Pin z extends downward between the forked ends of all the levers t, t1,etc. of both groups so that when an one of said levers is selectively oerated, al of the other levers will be rock by said pin for the purposedescribed.

Lever 30 is actually the 'long arm of a bell crank lever pivotallymounted on the machine frame (see Fig. 1). The other arm ofthis leverhas a pin which rides on a cam 71 on gear wheel 0, thereby, in cooration with a spring 73, giving lever 30 t e reciproca.-`

tory movement hereinbefore described. Gear wheel is geared one to onewiththe needle cylinder through an intermediate gear 72.

Reci rocating lever 30 carries a pawl 32 (see Flgs. 1, 3 and 5) thatimparts an intermittent progressive movement to a ratchet wheel 33 on ashaft carrying two pattern chains 35 and 36. The attern chains areprovided-with removable ugs of four different heights.

Selections of the lower group of levers t,

t, t and t are made in the following manner (see Figs. 3, 4 and 5) Lugson thepattern chain 35 are ,adapted to engage a cam mem` ber 41 carriedon a yoke-shaped lever 42 (see Fig. 5) on the end of which is mountedthe selector 21. This lever 42 is plvoted to a bracket 48. The lever 42is normally down in a osition where the selector 21 is inactive, butismovable into fo'ur different positions,

y thereby causing the selector to align with any one of the four leverst4, t, t and t by the action of the different height lugs on the patternchain on cam 41.

Selections of the upper group of levers t, t1, 132,# are made asfollows: Lugs on .the pattern chainv 36 are adapted to engage4 a cam 43carried on a lever 44 which is pivoted at 45 to a bracket on the machineframe. A yoke-shaped lever 46, which carries the selector 20, is pivotedto the bracket 48. This lever 46 rests upon an adjusting screw 47 inlever 44, which in turn rests upon an adjusting screw 49 carried bybracket 48. Lever 46 is normally down so that selector 20 is inactive,but the selector may be caused to align with any one of the levers t,t1, t and t by the action of the different height lugs on the patternchain 36 on cam 43 of lever 44.

It is obvious that by positioning the lugs on the pattern chains, theselectors may be shifted to actuate any predetermined chains of leversat each course of knitting, and that thereby jack cams g, g1', etc.,maybe moved into and out of action in suchmanner as to produce any desiredpattern.

I have not herein described the means for arresting the movement of thepattern chain during the knitting of the heel and toe. Such means,forming no part of the present invention, are described in a copendingapplication Serial No. 110,311, Patent No. 580.

As hereinbefore mentioned, it is decidedly advantageous to have all ofthe needles in perfect alignment during heel and toe knitting and alsowhen a transfer ring is to be placed on the needles for the purpose oftransferring a rib top. I have therefore pro-- vided additionalmechanism which will insure al1 of the cams g, g1, etc., being inactiveat these desired periods irrespective of whether the pattern mechanismwould normally render certain of these cams active at such times or not.This desired result I accomplish in the following manner. Pivotedbetween its ends on the machine frame, at 80, is a lever 81 (see Figs.2, 3 and 4), one arm of which is bent down and extends under the mainpattern disc 82 in the path of a cam 83 fastened to the underside ofsaid disc. This disc is intermittently ratcheted and controls` theknitting of the various parts of the stocking, including the knitting ofthe heel and toe portion and the leveling of the needles fortransferring, in a manner which is well known in the art. Extendingupward from lever 81 is a bent arm 84 which passes over and above leversn, n1, etc. When lever 81 is rocked by cam- 83, the arm 84 pushesagainst a lever 85 which is pivoted at z', and by means of a dependingpin 86, which passes in front of the eight levers y', swings any of suchlevers which at the time may be in the active position to the inactiveposition and holds all the levers 7' inactive notwithstandin anyoperation of any lever n which woul normally operate its correspondinglever y' to move its corresponding cam into operative position. When cam83 passes from under lever 81, lever 85 is released from arm 82 andlevers j again come under control ofthe pattern mechanism described.

It is obvious that by placing cams 83 in various positions on thepattern'disc 82, 'the pattern mechanism may be, whenever desired,rendered inoperative to press needles out of line.

Having now fully described my invention, what I claim and desire toprotect by Letters Patent is: y
